Description

Technical Field

[0001] The present invention relates to the field of oral orthodontics, and in particular to an oral teaching model and a use method thereof. Background Art

[0002] During tooth growth, due to the influence of genetic and environmental factors, teeth may be unevenly arranged. Orthodontic treatment is usually used to correct these uneven teeth. During orthodontic treatment, fixed or removable appliances are usually used to apply external force to the target teeth to move them to the correct position. During treatment, the appliances apply forces of different directions and magnitudes to the teeth to achieve the treatment goal. Understanding the principle of tooth movement is the basis for orthodontists to conduct clinical treatment, and it is also an important lesson for oral medicine students to learn orthodontics. The current teaching model consists of a base, a wax dam and a plastic tooth. The wax dam is directly stacked on the base, and the plastic tooth is inserted into the wax dam. The wax dam is softened by heating to achieve the movement of the teeth in the wax dam. The model is limited by the material and physical properties of the wax, and the initial state cannot simulate complex tooth dislocation; the tooth movement process needs to be heated by a water bath. If the time is too short, the teeth cannot move. If the time is too long, the wax dam is deformed and the teeth are easy to fall out. In addition, the range of movement cannot be accurately controlled, the operation is complicated, and the teaching effect is limited. Therefore, a new teaching model that simulates tooth movement is needed in oral orthodontic teaching to improve the teaching effect. Summary of the invention

A locking position is formed between the locking portion and the fixing portion, and a part of the spherical joint is located in the locking position, and the locking portion and the fixing portion are locked. The locking position is locked to limit the rotation of the spherical joint in the rotating groove; the locking position is unlocked by separating the locking portion from the fixing portion, so that the spherical joint can rotate in the rotating groove.

[0024] This innovative mimic tooth design cleverly combines the inflated airbag with the slot to achieve multi-angle rotation of the mimic tooth. This unique structural design allows the airbag to rotate freely in the slot, allowing the mimic tooth to simulate a variety of misalignment states. The breakthrough of this technology is that it overcomes the limitations of traditional oral models, which are usually unable to simulate complex tooth states, such as deviated dental arches, impacted teeth, etc., or require customized tooth arrangement models for each different patient. Now, by using a set of multifunctional models, we can accurately perform different malocclusions. The simulation of tooth misalignment in the oral cavity of patients with deformed types not only improves the accuracy of the simulation, but also significantly reduces the number of models required to achieve the same function, thereby saving the cost of teaching and treatment and improving work efficiency.

[0025] In addition, by adjusting the size of the airbag to change the resistance between the airbag and the side wall of the slot, the simulated tooth can move under a certain force, thereby simulating the movement of teeth under force during orthodontic treatment. Not only can it simulate tooth movement under different periodontal conditions, but it can also set different resistances for individual teeth to help understand the movement principle of orthodontic treatment and the clinical treatment process. This progress is undoubtedly a huge leap forward for oral education and clinical treatment. BRIEF DESCRIPTION OF THE DRAWINGS

[0050] In addition, the terms "first", "second", etc. are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first", "second", etc. may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0051] The inventor of this patent found that the existing tooth models in the prior art cannot meet the needs of simulating the complex oral conditions of patients because the tooth models in the prior art are often made in an integrated manner and are fixed in setting. Or, typically, they may also be designed as detachable models of a single tooth.

[0052] Such models are often used to teach the arrangement and shape of teeth in the oral cavity during teaching. Since teeth themselves do not have the freedom of movement, doctors cannot accurately reproduce the patient's tooth growth status under various abnormal conditions in one model. This cannot meet the teaching needs of orthodontic departments.

[0053] In view of this, the embodiment of this patent provides an oral teaching model to solve the above problems.

[0054] Example 1

[0055] like Figure 1 , Figure 6 As shown, in one embodiment, an embodiment of the present invention provides an oral teaching model, comprising: a simulated tooth 2, an airbag 1 and a base 400. The airbag 1 is connected to the simulated tooth 2 through a connecting rod, and the base 400 has a slot. The airbag 1 is embedded and installed in the slot, and the airbag 1 can be inflated and abutted against the inner surface of the slot to fix the orientation of the simulated tooth 2 by fixing the orientation of the connecting rod.

[0056] In this ingenious design, the mimic tooth 2 is connected to the airbag 1 through a connecting rod, and the airbag 1 is cleverly embedded in the slot. When the airbag 1 is inflated and expanded, its side wall is in close contact with the inner wall of the slot, effectively limiting any rotation of the airbag 1. This contact not only stabilizes the airbag 1, but also ensures the correct posture of the connecting rod and the mimic tooth 2, thereby achieving precise control of the orientation of the mimic tooth 2.

[0057] Specifically, when the airbag 1 is not inflated, due to the lack of internal air, the volume of the airbag 1 is reduced and it can move freely in the slot, almost unaffected by friction. At this time, the operator can easily adjust the mimic tooth 2 to the predetermined position. Once the mimic tooth 2 reaches the target position, it can be inflated to fix its posture. In addition, the elastic design of the airbag 1 allows it to deform moderately when subjected to external forces. Even in the inflated state, the orientation of the mimic tooth 2 can be adjusted by applying greater force to adapt to different usage scenarios.

[0058] Specifically, the cross section of the bottom of the groove body is arc-shaped. The bottom of the airbag 1 is spherical, and the side wall of the airbag 1 has friction lines.

[0059] When the airbag 1 is inflated, these friction lines are in close contact with the side wall of the slot, forming a stable interface. This ingenious design allows the airbag 1 to be firmly locked in the slot after inflation, preventing any unnecessary rotation. More importantly, the spherical bottom of the airbag 1 can rotate freely in the slot under the action of external force, and the friction lines ensure that the posture after rotation - that is, the position and posture of the airbag 1 - is reliably fixed.

[0060] The spherical bottom of the airbag 1 complements the arc-shaped bottom of the slot body. The spherical bottom not only increases the contact area with the bottom of the slot body, but also provides additional support. This design makes the external force on the bottom of the airbag 1 more uniform and stable, thereby ensuring that the posture of the airbag 1 in the slot body remains stable. When adjusting the posture of the mimic tooth 2, the spherical bottom design of the airbag 1 is easy to rotate, making the adjustment of the direction of the airbag 1 simple and direct.

[0061] In addition, the friction between the wall of the airbag 1 and the inner wall of the slot body is crucial to the stability of the posture of the airbag 1. The presence of friction lines significantly increases the friction coefficient between the airbag 1 and the inner wall of the slot body after inflation, which means that when the internal pressure of the airbag 1 remains unchanged, the friction between the airbag 1 and the slot body also increases. This enhanced friction ensures that the posture of the airbag 1 in the slot body can be more stable after being fixed, effectively preventing the unexpected changes in the posture of the simulated tooth 2 due to external forces, and providing reliable guarantees for the precise posture setting of the simulated tooth 2 during the teaching of orthodontics.

[0062] In addition, a plurality of limiting members 42 are arranged at intervals in the groove body; the airbag 1 is embedded between two adjacent limiting members 42, and the limiting members 42 can limit the sliding range of the airbag 1 in the groove body.

[0063] Once the airbag 1 is embedded in the slot, it can move freely in the space provided by the slot. Since the internal space of the slot is relatively large, the range of motion of the airbag 1 is also correspondingly enlarged, which may lead to positioning challenges when there is no appropriate positioning mechanism. The diversity of teeth - different types and sizes, and their specific growth positions in the mouth - requires that the simulated teeth 2 can be accurately installed in the corresponding positions of the simulated mouth. In order to solve this problem, the present embodiment introduces a restriction 42 to reduce the activity space of the airbag 1 in the slot, which not only speeds up the speed at which the airbag 1 finds its corresponding position, but also adjusts the orientation of the simulated tooth 2 by rotating the airbag 1, thereby ensuring the accuracy of the target direction.

[0064] In order to further improve the teaching effect, sensors can be integrated inside the slot to monitor the position and state of the airbag 1 in real time. These sensors can provide real-time feedback to assist teaching staff in adjusting the position of the airbag 1, so that the simulated teeth 2 can more accurately simulate the real oral condition, enhancing the interactivity and practicality of the teaching process. The technical solution of this embodiment not only improves the accuracy of the teaching tool, but also provides learners with a more intuitive and dynamic learning experience.

[0065] Example 2

[0066] In Example 1, an oral teaching model is provided, which simulates the growth of various teeth in the oral cavity by rotating the airbag 1 in the slot body, so as to be used for teaching oral orthodontics. However, due to the diversity of tooth growth, especially the deviation between the tooth body and the root, it is still difficult to simulate these complex situations by simply relying on the freedom of the airbag 1.

[0067] In view of this, if Figure 5 In the embodiment 2 of the present invention, the connecting rod includes: a rod body 13, a spherical joint 12 and a fixed base 11. The rod body 13 is connected to the mimic tooth 2. The spherical joint 12 is connected to an end of the connecting rod away from the mimic tooth 2. The fixed base 11 also includes: a fixing member fixed on the airbag 1; a rotation groove is opened on the fixing member, and the spherical joint 12 is arranged in the rotation groove and can rotate freely in the rotation groove.

[0068] The spherical joint 12 is connected to the fixing part on the airbag 1 through the rod body 13 and can rotate freely in the rotation groove. This allows the rod body 13 to rotate relative to the fixing part, thereby achieving accurate positioning and angular swing adjustment of the simulated tooth 2. When the airbag 1 plays the role of the tooth root, the rotation of the spherical joint 12 can simulate the angle difference between the tooth root and the tooth, thereby accurately reproducing the growth between different teeth and the tooth root. This simulation capability greatly improves the accuracy and practicality of orthodontic teaching.

[0069] In this way, the simulated tooth 2 can be subtly tilted relative to the air bag 1 to simulate the natural position and posture of the tooth in the mouth. This not only helps to better understand the growth pattern of teeth, but also provides a more intuitive reference for orthodontic teaching.

[0070] Furthermore, the fixing member further comprises: a friction component. The friction component is arranged on the groove wall of the rotation groove, and is used to increase the friction force received by the spherical joint 12 when rotating in the rotation groove, so as to limit the rotation of the spherical joint 12 .

[0071] The design of the spherical joint 12 is crucial because it needs to maintain a stable posture after rotation to ensure the correct orientation of the rod body 13 and the simulated tooth 2. The friction component is in close contact with the outer surface of the spherical joint 12. When the spherical joint 12 rotates, this contact significantly increases the friction coefficient, thereby enhancing the friction force on the spherical joint 12. This enhanced friction force is crucial to maintaining the stability of the simulated tooth 2 because it ensures that the simulated tooth 2 will not easily deviate from its set simulation posture even under the action of external forces.

[0072] In this way, the simulation system of this embodiment can not only maintain the stability of the simulated tooth 2, but also make precise adjustments when necessary, thereby improving the quality and effect of orthodontic teaching. The cleverness of this design lies in that it combines functionality and adjustability, making the teaching process more intuitive and efficient, while also providing learners with a more realistic operating experience.

[0073] Example 3

[0074] In the second embodiment of the present invention, a mechanism is provided in which the ball joint 12 of the connecting rod rotates in the rotation groove of the fixing part, and this mechanism can realize the deflection of the simulated tooth 2 relative to the air bag 1 to simulate a richer tooth growth situation. In this process, in order to ensure the stability of the posture of the simulated tooth 2, we need to increase the friction between the ball joint 12 and the rotation groove.

[0075] However, since the teaching model needs to simulate a variety of different tooth growth conditions, the rotation frequency of the spherical joint 12 in the rotating groove is quite high. This high-frequency rotation may cause wear of the friction parts, thereby affecting the posture stability of the simulated tooth 2. In addition, frequent replacement of friction parts will not only increase maintenance costs, but may also cause trouble to the teaching progress and equipment maintenance.

[0076] In view of this, in the third embodiment of the present invention, the fixing member further comprises: a locking assembly, the locking assembly comprising: a fixing portion and a locking portion, fixed in the notch of the rotation groove. A locking position is formed between the locking portion and the fixing portion, and a part of the spherical joint 12 is located in the locking position, and the locking portion and the fixing portion are locked. The locking position is locked to limit the rotation of the spherical joint 12 in the rotation groove; the locking position is unlocked by separating the locking portion from the fixing portion, so that the spherical joint 12 can rotate in the rotation groove.

[0077] The rotation of the spherical joint 12 in the rotating slot plays a key role in accurately setting the orientation of the mimic tooth 2. The operator will carefully adjust the spherical joint 12 until the mimic tooth 2 points to the target direction. Once the desired orientation is achieved, the spherical joint 12 is fixed in place by tightly locking the fixing portion of the rotating slot with the locking portion, thereby ensuring that the orientation of the mimic tooth 2 will not change due to external forces.

[0078] Specifically, the fixing part can be designed as a semicircular structure, which can be completely fixed at the notch of the rotating groove, and the locking part is a detachable semicircular part. When the fixing part and the locking part are combined and locked, they form a complete circular structure together, tightly abutting and wrapping the spherical joint 12. This design not only ensures the stability of the spherical joint 12, but also allows the rod body 13 to pass through the avoidance groove formed between the locking part and the fixing part, so as to facilitate the normal simulation activity of the simulated tooth 2.

[0079] In other embodiments, a rotational connection design is adopted between the locking portion and the fixing portion, which allows the ball joint 12 to be locked and released by a simple rotation operation. The advantage of this rotational connection design is that the locking portion will not be separated from the fixing portion even when the lock is released, thereby avoiding the loss of the locking portion and ensuring the consistency of the locking angle, reducing the risk of installation failure or increasing the difficulty of locking.

[0080] In order to further improve the locking effect, we added rubber parts to the contact surface between the locking part and the fixing part. When these rubber parts contact the spherical joint 12, they not only prevent direct friction between metal parts, but also significantly increase the friction force, thereby enhancing the locking effect. This design ensures that the posture of the simulated tooth 2 can remain stable even under the action of external forces, providing a reliable simulation effect for orthodontic teaching.

[0081] Example 4

[0082] refer to Figure 8 As shown, in Example 4 of the present invention, the oral teaching model also includes: an air supply mechanism. The air supply mechanism includes: an air supply pipeline 3, which is connected to the air bag 1 to fill the gas provided by the external air supply module into the air bag 1. The air supply mechanism also includes: a control module and an air pressure detection module. The control module is communicatively connected to the air supply module to control the start and stop of the air supply module. The air pressure detection module is communicatively connected to the control module to detect the air pressure value of the gas in the air bag 1, and transmit the detected air pressure value to the control module. The control module is used to stop the operation of the air supply module when the air pressure value reaches a preset air pressure value.

[0083] In the embodiment, once the orientation of the simulated tooth 2 is accurately confirmed, gas is filled into the airbag 1 through the air supply mechanism to expand it and firmly position it in the slot. In the actual orthodontic process, the tightness of the roots of different teeth is different, and this subtle difference has an important impact on the treatment results. In order to highly restore this real situation in the teaching model and enhance the realism of teaching, we can simulate different root firmness by adjusting the air pressure value injected into the airbag 1. Specifically, when the air pressure in the airbag 1 increases, the pressure exerted by its side wall on the inner wall of the slot increases accordingly, thereby enhancing the friction between the airbag 1 and the slot, making the posture of the simulated tooth 2 more stable. On the contrary, if the air pressure in the airbag 1 is reduced, the pressure of the airbag 1 on the slot is correspondingly reduced, the friction is reduced, and the posture of the simulated tooth 2 is easy to adjust, thereby simulating the situation of loose roots. Such a design enables the model to meet the needs of simulating various oral states, greatly improving the effect and quality of orthodontic teaching.

[0084] Furthermore, the control module can control the air supply module to fill the air into the air supply line 3, and inject the gas into the airbag 1 through the air supply line 3. At the same time, the air pressure detection module can detect the air pressure value inside the airbag 1 and provide real-time feedback. A preset value of air pressure is set in the control module. When the air pressure detection module detects that the air pressure value in the airbag 1 reaches the preset value, the air supply module is controlled to stop supplying air to the air supply line 3. This fine control process not only ensures that the airbag 1 can be tightened in the slot to achieve accurate simulation of tooth growth, but also prevents damage to the airbag 1 that may be caused by over-inflation, thereby extending the service life of the teaching aid and maintaining the teaching quality.

[0085] Example 5

[0086] In Example 4 of the present invention, an innovative air supply mechanism design is proposed, which can supply air to each air bag 1 in the model separately. By injecting gas with different air pressure values ​​into the air bag 1, the specific conditions of various teeth can be simulated. However, in oral orthodontic treatment, it is usually necessary to use the surrounding teeth to apply appropriate force to the target teeth to achieve the orthodontic effect. Therefore, a complete oral environment model is crucial to the accuracy and effectiveness of teaching. This comprehensive model can not only provide a more realistic treatment scenario, but also help students better understand and master the complex process of orthodontic treatment, thereby improving the quality of teaching.

[0087] In view of this, if Figure 1 , Figure 2 , Figure 3 , Figure 4 The base 400 shown in Example 5 of the present invention is: a simulated gum 4, and a plurality of grooves are sequentially connected and arranged on the simulated gum 4 to form a main track 41. The airbag 1 slides along the main track 41 and is fastened to the main track 41 after being inflated. The oral teaching model also includes: an air supply mechanism. The air supply mechanism includes: an air supply pipeline 3, which is connected to the airbag 1 to fill the gas provided by the external air supply module into the airbag 1. The simulated gum 4 also includes: an inflation tube guide track 43, which is arranged parallel to the main track 41, and the air supply pipeline 3 passes through the inflation tube guide track 43 from the outside of the simulated gum 4, and is connected to the airbag 1 arranged in the main track 41; the inflation pipeline can slide along the inflation tube guide track 43 to follow the sliding of the airbag 1.

[0088] The simulated gum 4, which is composed of a plurality of slots connected in sequence, can intuitively simulate the gum structure in the human mouth. These simulated teeth 2 arranged on the slots not only represent each tooth individually, but can also be fixed at a specific position on the simulated gum 4, thereby perfectly reproducing the oral environment required for the teaching objective. The simulated gum 4 forms a continuous main track 41 by connecting the slots, so that when installing the simulated teeth 2, we can easily insert the airbag 1 into both ends of the track and slide the simulated teeth 2 along the main track 41 until the simulated teeth 2 reach their predetermined positions. Once the simulated teeth 2 are in place, we can adjust their orientation, and inflate and fix them after confirming that the orientation is correct, to ensure that the simulated teeth 2 are in the correct position on the simulated gum 4, so that the tooth arrangement in various oral states can be accurately simulated.

[0089] The airbag 1 needs to be supplied with air through the air supply line 3. In order to restore the real situation of the oral cavity, multiple simulated teeth 2 will be set on the same simulated gum 4, so the airbag 1 corresponding to each simulated tooth 2 requires an independent air supply line 3. In addition, a mechanical sensor can be added to the airbag 1, and the mechanical sensor is connected to the control module for communication. The mechanical sensor monitors and feedbacks the squeezing force received by the airbag 1 in real time, so as to convert the interaction force between the simulated teeth 2 and the simulated gum 4 to better simulate the oral environment.

[0090] In order to optimize the space utilization and prevent mutual interference between the air supply lines 3, we designed inflation tube guide tracks 43 on the mimic gums 4. These tracks allow the individual air supply lines 3 to pass through and be directly connected to the external air supply components, thereby avoiding the accumulation of the air supply lines 3 in the main track 41, ensuring the free movement space of the airbag 1 in the main track 41, and eliminating the interference that the air supply lines 3 may cause to the movement of the airbag 1.

[0091] In order to prevent the air supply line 3 from getting tangled during the movement of the airbag 1, the design of the inflation tube guide track 43 matches the width of the air supply line 3, ensuring that the air supply lines 3 are neatly arranged when moving along the track, and avoiding the overlap and entanglement between adjacent air supply lines 3. Such a design not only improves the reliability of the system, but also enhances the practicality of the teaching model, making it an indispensable tool in orthodontic teaching.

[0092] In this embodiment, the main track 41 protrudes to one side so that the simulated gum 4 can closely match the shape of the main track 41. In order to maintain the intuitiveness of the teaching model when simulating the growth of teeth in the oral cavity, we set an air tube avoidance track on the concave side of the simulated gum 4. This avoidance track cleverly hides the air supply line 3 so as not to interfere with the visual effect of the model. In addition, since the arc of the simulated gum 4 at the concave part is smaller, the intervals between the air supply lines 3 are more compact, which not only makes it convenient for the operator to grab and organize the air supply lines 3, but also optimizes the overall user experience.

[0093] refer to Figure 7 As shown, in an embodiment of the present invention, there is also a method for using an oral teaching model, which is applicable to the above-mentioned oral teaching model. Specifically, the method for using includes:

[0094] S1. Move the simulated tooth 2 to make the airbag 1 move toward the target position along the main track 41 of the simulated gum 4.

[0095] S2, when the airbag 1 reaches the target position, adjust the orientation of the simulated tooth 2 so that the simulated tooth 2 presents the target posture.

[0096] S3. Inflate the airbag 1 to expand it and fix it tightly in the main track 41, and keep the simulated tooth 2 in the target posture.

[0097] Since the shape of each simulated tooth 2 can be set to be different, it can correspond to different types of teeth in the oral environment, and different teeth usually grow in different positions. The oral teaching model of this embodiment allows various simulated teeth 2 to be accurately moved to corresponding positions on the simulated gums 4. Once the simulated tooth 2 reaches its target position, its orientation can be adjusted to be consistent with the posture of the actual tooth, thereby achieving a true simulation of the oral situation.

[0098] Next, for the simulated tooth 2 that has completed posture adjustment, the airbag 1 behind it can be inflated. After the airbag 1 is inflated, it will be tightly abutted against the inner side walls on both sides of the main track 41, thereby firmly positioning the airbag 1. This process not only stabilizes the position of the simulated tooth 2, but also ensures the accuracy of its posture. Finally, the combination of the simulated tooth 2 and the simulated gum 4 accurately reproduces the environment inside the oral cavity, providing an extremely realistic model for teaching and demonstration.

[0099] In addition, the step of inflating the airbag 1 specifically includes:

[0100] S4, opening the gas supply mechanism to fill the airbag 1 with gas.

[0101] S5. In response to the full-gas signal of the airbag 1 , the gas supply mechanism is turned off to stop filling the airbag 1 with gas.

[0102] In an embodiment of the present invention, the expansion of the airbags 1 is achieved by internal inflation, so that they can be in close contact with the side walls of the main track 41 and stably fixed in the track. Therefore, once the simulated tooth 2 is put in place, it is necessary to supply air to the inside of the airbag 1 through the air supply mechanism to achieve its fixation. At the same time, it is crucial to monitor the air pressure in the airbag 1 in real time to ensure that when the air pressure reaches the preset target value, the air supply is stopped immediately to prevent the airbag 1 from being damaged due to over-inflation. In some cases, in order to simulate the tightness of different tooth roots, different fixing strengths of the airbag 1 can be achieved by adjusting the air pressure in the airbag 1, thereby accurately reproducing the firmness of different tooth roots.

[0103] Finally, the simulated gum 4 further includes: a plurality of airway restricting members 42. The plurality of airway restricting members 42 are detachably mounted on the air tube guide track 43 to isolate adjacent air supply lines 3 from each other.

[0104] The air tube restriction piece 42 is used to firmly snap into the inflation tube guide track 43 after the airbag 1 is inflated and reaches its target position. Specifically, the main function of the air tube restriction piece 42 is to effectively isolate the adjacent air supply pipelines 3, thereby preventing them from being entangled and crossed. In addition, due to the limiting effect of the air tube restriction piece 42, the air supply pipeline 3 is fixed in an appropriate position, which greatly facilitates the management and arrangement of the pipeline. This design not only improves the operating efficiency of the teaching aid, but also enhances the overall reliability of the system, ensuring the smooth progress of the teaching process.

It should be understood that the above description is only a specific embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
